Ya, I suppose the mainspring could be rapidly releasing tension. I suggest taking it to a watch repair shop and have them look at it.

My AT had the same issue. Take it back to the boutique, it may just need some lubrication like mine did. It's a pretty common thing with new ATs apparently.
So, this is a contemporary option but still very much reminiscent of neo-vintage styling. You should look at Nomos. Something like the Tangente, Metro, or even Tetra gives a lot of the same vibes as Orea. They do their own in-house manual wind calibers, which can be seen through optional saffire casebacks.
Nomos Club Campus or pre-order one of Farer's moonphase watches for next year.
Baltic watches are super solid. I wouldn't have any worries about buying from them.
3 - 5 atm is probably the range. More water resistant than water proof. The reason people think 3 atm can't handle a splash is largely marketting. Ya, maybe don't swim or shower with it on, but I wouldn't be worried about wearing it anywhere above the waterline.

They come up occasionally but they are a pretty niche and polarizing brand. Unless you are looking for a Bulgari, chances are a Bulgari isn't a relevant recommendation.
I don't own one but have had a chance to look at and wear one. They're nice. I don't disagree about the strap feeling a little cheap, but it wasn't enough to bother me. Personally, I'd go for their new California Dial version.
That said, I'd never buy an Alpina at full price. These are watches that feel like they were made to be sold for 40% on grey market sites.
Big steel sports watches are the sneakers/street wear of the watch world. They are tacky as hell and their popularity is driven largely by hype.
F91-W. It's low profile to fit well under your jacket cuff/gloves, it's strap will break before it breaks your wrist in a fall, and if you do damage it you won't be upset.
It's a Miyota 9015, which isn't a certified movement and is highly unlikely to ever be as accurate as +/-2 seconds a day. Their -5/+15 is what you should expect.
Hell, +/- 2 seconds a day is more accurate than CSOS or METAS Chronometre standards. You're going to have to start looking at some higher end pieces for that level of accuracy in a mechanical watch.
